Understanding Different Absolute Value Calculators from Real to Complex Numbers

Math is one of the most interesting subjects for the students. This subject is not only important for the different higher studies but also have some real life applications. From simple algebra to the top level mathematics like trigonometry and calculus, math plays a vital role in the different engineering fields. One can’t imagine innovations and scientific theories with the mathematical implementations.

But this important subject is somewhat challenging and complicated when the calculations grow bigger and bigger. Hence there is need of the different type of calculators. These calculators are the automated tools that help us in solving huge and complex problems. We can use both online and offline calculators to solve this complex subject.

In this article, we will be discussing the different methods that act as the base of absolute value calculator. But before going to calculators let’s first understand what the absolute value of any number is. We are all familiar with the number line that has 0 in the mid and a range of positive and negative numbers on its RHS and LHS respectively. The absolute value of any number let say ‘x’ is defined as the distance of ‘x’ from zero. Using the modulus symbol, we can define |-2| be equal to 2.

1.    Hence our first method to solve the different absolute values is determining the distance of the number from 0 on the number line. It doesn’t matter if it’s positive or negative, the absolute value of the number will always be positive. Hence for the examples stated below the absolute value calculator will give following values:
·         |3|= 3
·         |-5|= 5
·         |0|=0; because there is no other number between 0 and 0; hence it’s 0 itself.
2.    While you are going for the complex numbers in the form of ‘z=x+iy’ then, in that case, there is a particular formula that comes into action for finding the absolute values. This formula has been stated as follow:
|z|=|x+iy|= =
The above equation acts as the base of the different online absolute value calculators.
3.    Another type of problem that occur while finding the absolute value are the different equations in the form of (x+2=8). When you need to solve such equations that the following steps are taken:
·         First of all, we will divide the equation into 2 parts with both positive and negative values on the RHS let say 8 and -8 as stated in the example above.
·         Then we will solve the equation and get the value of ‘x’ in the both cases.
·         Finally, we will plot the values on the number line, and that will be the range of the absolute values of the following equation.
But as said earlier, the absolute value is always positive.

There are many functions like trigonometric functions, sign function, etc. that has different absolute values. There are many laws, or we can say proved theories about absolute values that help in the working of absolute value calculator. These online calculators are quite efficient and correct for giving results. One can not only solve the problems, but with the help of step by step guides, one can learn as well.

The List: Free Online Calculators
Basic Calculators
Basic online calculators like a system of equations calculator allow you to perform arithmetic calculations, as well as find square root values and percentages.
quickmath.com is a super simple and convenient basic online calculator. It has a great user interface and doesn't require you to download anything. So, if your homework involves lots of adding, subtracting or finding percentages, this is a no-nonsense solution for you.

Bottom line: basic, big, bold and easy to use.
Scientific and Algebraic Calculators
Scientific calculators do the same things as basic calculators, but they also allow you to perform operations with exponents, logarithms, trigonometric functions and more.
There are dozens of free scientific calculators out there, and it's easy to get lost in the jungle. Here are a few that most students find convenient and easy to use:
  • The scientific system of equations calculator from quickmath.com. This is a simple scientific calculator that resembles a handheld calculator. The interface is a little small, but other than that, it's a great tool if you want to simply push buttons rather than input a bunch of mathematical symbols.
Bottom line: a traditional looking scientific calculator that doesn't require you to enter a bunch of "keyboard gibberish."
  • The online system of equations calculator by David Sumner of the University of South Carolina. This calculator is awesome! You can enter the entire algebraic expression and click "evaluate," and the calculator will return the answer. The downside to some may be that it doesn't have that traditional calculator look and there are no buttons, but there are sufficient instructions below the calculator that explain how to input the expressions correctly.
Bottom line: helps solve long algebraic expressions instantly (as long as you don't mind the "keyboard gibberish").
  • The complete calculator from quickmath.com. This site offers a comprehensive calculator that spans multiple math disciplines - from arithmetic to calculus. It will help you perform operations with fractions, logarithms, limits, trigonometric functions and more. It also has a separate tab for graphing.

These calculators are free to use and give you the ease to check out the results as soon as possible. So, start using them and carry out the calculations to be solved in seconds. These calculators will surely be a boon to your mathematics and will show you the way out of the difficult mathematical calculations that you have never thought to crack yet.
